I got a reply from GON pretty quickly, less than 24 hrs after sending the initial message. I asked him if he could do the jailhouse blue mod too, and he said he needed pictures to see if he could. - But he only has cherry blues, I think, not gateron blues.
I'd have to coordinate him getting the other switches some how, which could be a huge headache, if even something he'd be into. Furthermore, the case disappointment is a big factor. And it's not like I could easily replace the case at any time either, since the plate that everything is soldered through is for that acryllic case specifically, right?
